As far as I know this planetary thing in Vue does not mean you can have the kind of infinitely vast levels of scale shown on nvseal's image.
Also, TG2's level of surface detail in the renders seems very good (somehow) compared to Mojoworld and Vue.
However, I see elements of procedural processing going on in Vue 7.5 that TG2 is not capable of without at least some more functions such as a proper curve graph and colour gradient. Stuff that Mojo is capable of.
